Add support for wildcards or regex in Agent Scopes

[proschowsky]

Creating and maintaining scopes when using Agno with RBAC can be cumbersome.

I would be helpful if the scopes for agents supported wildcards or regex as a way to assign access to multiple agents with a single scope.

E.g. agents:marketing.*:read would give access to all agents with ids that start with marketing.

agents:<agent-id>:read | View a specific agent
agents:<agent-id>:run | Run a specific agent
